Supplements During IVF: What Helps and What to Know
Going through IVF is one of the most emotionally intense things a person can do. You are already following your clinic's protocol carefully. Now you want to know: is there anything else you can do to help? The answer is yes — with one big rule. Your RE's protocol is the plan. Supplements are like optimizing your soil before planting. They do not replace the gardener, and they do not override the protocol. Always clear every supplement with your reproductive endocrinologist before you start. With that said, here is what the research supports.
What supports egg quality before retrieval?

CoQ10 is the most researched supplement for IVF preparation. It lives inside egg cells and helps them make the energy they need to divide correctly after fertilization. Think of it as fuel for the egg's engine. Studies in women doing IVF — especially those with poor ovarian response or diminished ovarian reserve — show CoQ10 can improve egg number and embryo quality. Most protocols use 400–600 mg daily starting two to three months before retrieval. Methylfolate (the active form of folate) is also critical — the egg uses it immediately at fertilization to copy DNA correctly. A quality prenatal with methylfolate is a strong baseline.
What supports the uterine lining?

After retrieval comes the transfer — and that means preparing your uterine lining to receive the embryo. Vitamin E (as mixed tocopherols) improves blood flow to the uterus, which helps the lining thicken and become receptive. Some studies show it improves lining thickness in women who have struggled with thin linings. Vitamin D has a direct role in uterine receptivity — your uterine lining has vitamin D receptors, and low levels are linked to lower implantation rates. L-arginine is an amino acid that also supports uterine blood flow. All of these should be discussed with your RE before adding them to your protocol, as some may interact with medications.
What should I avoid during IVF?
A few things are worth avoiding during an active IVF cycle. High-dose melatonin is sometimes used in IVF protocols, but only under clinic supervision — do not add it yourself. Herbs like vitex, ashwagandha, and maca can affect hormone levels and should be stopped during an active cycle unless your RE specifically approves them. High-dose vitamin C (over 1000 mg) may interfere with follicle development in some studies. The basic rule is: if your RE did not put it in the protocol, ask before taking it. Simple prenatal, CoQ10, and vitamin D are generally the safest additions and the most evidence-backed.
The bottom line
IVF asks a lot from your body and your spirit. Every small thing you can do to optimize conditions matters — and supplements, used thoughtfully, are one of those things. Selene is designed to fill the nutritional gaps that matter most at each stage of this process. Always work with your RE, bring your supplement list to every appointment, and trust that you are doing everything you can.
Questions
Should I tell my RE about every supplement I am taking?
Yes, absolutely. Bring a complete list to every appointment. Some supplements interact with IVF medications. Your RE cannot advise you properly if they do not know the full picture. This is not optional — it is important for your safety and your outcome.
Is DHEA safe to take before IVF?
DHEA is sometimes recommended for women with diminished ovarian reserve, but only under medical supervision. It is a hormone precursor and can cause side effects. Do not take it unless your RE specifically prescribes or approves it — it is not a routine supplement.
Can supplements improve a poor prognosis?
They can improve the conditions your eggs and uterus are working in. They cannot overcome severe diminished ovarian reserve or other structural issues. Think of them as optimization, not transformation. Starting early and being consistent gives you the best chance of a meaningful benefit.
When should I stop supplements before egg retrieval?
Follow your clinic's instructions exactly. Many clinics ask you to stop all supplements except your prenatal a few days before retrieval. Some allow CoQ10 throughout stimulation. There is no universal rule — your protocol is the answer.
